Explanation Given info: α = 0.01 , x 1 = 141 ( = 47 % of 300 ) , n 1 = 300 , x 2 = 141 ( = 47 % of 300 ) , and n 2 = 300 . Calculation: The hypotheses are given below: Null hypothesis: H 0 : p 1 = p 2 Alternative hypothesis: H a : p 1 ≠ p 2 Here, the test is two tailed test. Critical value: Step by step procedure to obtain the critical value using the MINITAB software: Choose Graph > Probability Distribution Plot choose View Probability > OK. From Distribution , choose ‘ Normal ’ distribution. Click the Shaded Area tab. Choose probability Value and Two Tail for the region of the curve to shade. Enter the probability value as 0.01 . Click OK . Output using the MINITAB software is given below: From the output, the critical value is ±2.576. Rejection region for a two-tailed test: If z < z 0 ( = − 2
